That would be actually Great, But there\'s many reasons to not Implement this in Browser games, A player can abuse it by using more than 1 account to farm stuff for his/her main account therefore It would make Imbalance between normal players and farmers, And as far as I know, I Haven\'t seen alot of Browser games that have this feature.
This Feature Trade Would actually benefit If It\'s a Huge game Let\'s say for example Tera,World Of warcraft and these kind of MMO games, which they\'re actually MMO not like Magerealm Since It\'s called MMO But it\'s actually Solo game...
Also You can easily Build yourself here Not like Other Big Downloadable MMOs, which requires from 6 months to years to be strong.
Anyways Great Suggestion, But Inorder for this to be implemented It must have Rules, So that way it would prevent Farming.

Best Thing Is to Remake Auction house in this game and make it reasonable and working Method to sell & buy from players.
